Mbappe reveals he tells himself he is better than two of the best players of this generation Lionel Messi and Cristiano Ronaldo in order to motivate himself before matches.
The 22-year-old has been tipped as one of the players to take over from Messi and Ronaldo as the best player in the world and he is currently living up to the hype.
“The ego? Of course, it's important because when you're in the rough, no one else is going to push you," Mbappe told RMC Sport. "And you have to convince yourself that you are capable of toppling mountains.
"People don't understand ego but when you are not well there is no one who will come to your house to tell you that you can do that.
“It's just you and your mindset. It's just you. You have to convince yourself that you are capable of doing great things.
"Every time I go on a pitch I always tell myself that I'm the best and yet I have played on grounds where there was Messi and Cristiano Ronaldo.
“They are better players than me, they have done a billion more things than me. But, in my head, I always tell myself that I'm the best because that way you don't give yourself limits and you try to give your best."
The 2014 World Cup winner added: "Of course, sometimes people do not understand because I think there is perhaps also this barrier which is created in relation to this subject, where one does not really explain what the ego is.
"For people, the ego is just not giving a friend a penalty, having a better salary than the player of the rival team. It's not just that, it's also in the preparation. It's a personal thing, to surpass yourself, it's way beyond that superficial thing of saying 'me, me'. But I think there is quite a bit to be said about it."
Mbappe is currently having another stellar season with the Parisians in the French Ligue 1 and Champions League.
He has scored 30 goals and provided nine assists in all competitions for Paris Saint-Germain so far.
